There is a recursive stack overflow in clamav 0.93.3 and 0.94 (and probably
older versions) in the jpeg parsing code.
it scan[]s the jpeg file, and if there is a thumbnail, it'll scan that too. the
thumbnail itself is just another jpeg
file and the same jpeg scanning function gets called without checking any kind
of recur[]sing limit. this can eas[i]ly
lead to a recurisive stack overflow.
